This week we reviewed more about evolution and then focused on the origin of life. We learned about two prominent theories of how life first arose on earth, the reproduction-first and the metabolism-first theories. We used these worksheets to read about them. After reading about these theories, I couldn’t help but wonder if we could replicate this process artificially. If we can figure out how life first evolved on earth, could we give rise to an entirely new tree of life that nothing on earth has relation to?

We also joked about how a large percentage of people still do not accept evolution as the source of all species. How do they believe this? Do they deny the existence of evolution purely on religious grounds or do they not believe the evidence for it? Or is it that they were never taught the concept of evolution correctly and they don’t have a good understanding of it?
